Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen with a backlight assembly. Background Art

[0002] The backlight source is mainly composed of a light source, a light guide plate, an optical film, a plastic frame, etc. The backlight source has the characteristics of high brightness, long life, and uniform light emission. At present, there are three main types of backlight sources: EL, CCFL, and LED. According to the different distribution positions of the light source, they are divided into edge-lit and direct-lit types. As LCD modules continue to develop towards brighter, lighter, and thinner directions, edge-lit CCFL backlight sources have become the mainstream of backlight development;

[0003] Generally, LED light source modules are glued to the backlight module by glue. After long-term use, the glue is easy to fall off, which will affect the use of the equipment. At the same time, the light source module is fixed by glue, and there will be certain difficulties when the display needs to be disassembled for maintenance. Therefore, we have launched a new LCD screen with a backlight assembly. Utility Model Content

[0011] By adopting the above technical solution: the adjusting bolt is movably connected with the clamping plate, it can be prevented that the clamping plate causes wear to the module when the adjusting bolt is rotated.

[0012] Preferably, the adjusting bolt is threadedly connected to the adjusting hole, and the clamping plate is located inside the receiving groove.

[0013] By adopting the above technical solution: the clamping plate is located inside the storage groove, so that the front end of the clamping plate can be hidden behind the rear wall of the fixed frame, preventing multiple modules from being scratched against the clamping plate when being installed.

[0016] Preferably, the top plate is located inside the storage chute and is slidably connected to the storage chute.

[0017] By adopting the above technical solution, the top plate located inside the storage chute can be limited by the storage chute to prevent the top plate from slipping off the storage chute during use and affecting subsequent use.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. In the present invention, a fixing frame is provided in the device, and a plurality of clamping mechanisms are provided around the rear wall of the fixing frame.

[0034] A liquid crystal display screen with a backlight assembly comprises a fixed frame 1, a transparent protective layer 2 is fixedly connected to the front end of the fixed frame 1, a support frame 3 is fixedly connected to the middle part of the lower end of the fixed frame 1, a first slide groove 4 is opened in the middle part of the upper end of the fixed frame 1, a second slide groove 5 is opened in the front wall and the rear wall of the first slide groove 4, a cover plate 6 is slidably connected to the inner surface of the first slide groove 4 and the inner surfaces of the two second slide grooves 5, a fixing hole 7 is opened to the left side of the upper end of the cover plate 6 and the left side of the lower wall of the first slide groove 4 and the right side of the upper end of the cover plate 6 and the right side of the lower wall of the first slide groove 4, fixing nails 8 are threadedly connected to the inner surfaces of the two fixing holes 7, a display module 9 and a backlight module 10 are inserted and connected to the inner surface of the fixed frame 1, a light source assembly 11 is clamped and fixedly connected between the display module 9 and the backlight module 10, the display module 9 is located in front of the backlight module 10, and the support frame 3 is located between the two ejection mechanisms 12 and does not contact them.

[0035] In this embodiment, a plurality of clamping mechanisms 101 are arranged on the inner rear wall of the fixed frame 1, and the plurality of clamping mechanisms 101 are distributed in an array at equal distances and do not contact each other. Ejection mechanisms 12 are arranged on the left side and the right side of the lower wall of the fixed frame 1, and the two ejection mechanisms 12 do not contact the plurality of clamping mechanisms 101. The display module 9 is located in front of the backlight module 10, and the support frame 3 is located between the two ejection mechanisms 12 and does not contact them. The clamping mechanism 101 includes an adjusting bolt 111, and a clamping plate 112 is movably connected to the front end of the adjusting bolt 111. A plurality of storage grooves 113 are opened on the inner rear wall of the fixed frame 1, and adjustment holes 114 are opened in the middle of the inner rear wall of the plurality of storage grooves 113.

[0036] Through the above scheme: by arranging multiple clamping mechanisms 101 around the inner rear wall of the fixed frame 1 in the device, the display module 9 and the backlight module 10 are supported and fixed by multiple clamping mechanisms 101, which not only simplifies the installation process, but also prevents the loosening of multiple modules due to glue oxidation after long-term use.

[0037] In this embodiment, the ejection mechanism 12 includes a top plate 121, and storage grooves 122 are provided on the left and right sides of the lower wall of the fixed frame 1. A through hole 123 is provided in the middle of the lower wall of the two storage grooves 122. The top plate 121 is located inside the storage grooves 122 and is slidably connected to the storage grooves 122.

[0038] Through the above scheme: by arranging two ejection mechanisms 12 on the lower wall of the fixed frame 1, when the device needs to be disassembled and maintained during use, the cover plate 6 on the upper part of the fixed frame 1 can be opened, and then the multiple clamping mechanisms 101 can be loosened, and finally an ejection tool is used to pass through the through hole 123 in the ejection mechanism 12 to lift the top plate 121, so that the display module 9 and the backlight module 10 inside the fixed frame 1 can directly slide out of the fixed frame 1 through the lifting of the top plate 121, so that the display module 9 and the backlight module 10 can be separated from the fixed frame 1 very conveniently.

[0039] It should be noted that the utility model designs a liquid crystal display screen with a backlight assembly, and its core feature lies in its unique assembly and disassembly mechanism. By introducing a fixed frame 1, the device allows the display module 9, the backlight module 10 and the light source assembly 11 to be conveniently and quickly attached to each other and fixed during assembly. Specifically, a plurality of clamping mechanisms 101 are arranged around the inner rear wall of the fixed frame 1. These mechanisms adjust the position of the clamping plate 112 by twisting the adjusting bolt 111, thereby supporting and fixing the display module 9 and the backlight module 10 to ensure that they are tightly fitted. After the assembly is completed, the cover plate 6 is connected to the fixed frame 1 by the fixing nails 8 to achieve sealing and fixation of the overall device.

[0040] This design not only simplifies the installation process and improves production efficiency, but also effectively avoids the problem of module loosening caused by glue oxidation after long-term use through the top support fixation of the clamping mechanism 101. In addition, the two ejection mechanisms 12 arranged on the lower wall of the fixed frame 1 provide great convenience for the disassembly and maintenance of the device. When disassembly is required, it is only necessary to open the cover plate 6, loosen the clamping mechanism 101, and then use the ejection tool to pass through the through hole 123 of the ejection mechanism 12 to lift the top plate 121, so that the display module 9 and the backlight module 10 can easily slide out of the fixed frame 1 through the top plate 121, thereby realizing the rapid separation of the module from the fixed frame 1.
